URBANA - Champaign County authorities say a Mahomet registered sex offender has been arrested for allegedly molesting a girl under the age of 13.

The 33-year-old man is being held on $500,000 bond, and authorities say they expect to formally charge the man with predatory criminal sexual assault of a child on Monday.

According to Champaign County Sheriff's Sgt. Tony Shaw, the girl reported inappropriate contact she allegedly had with the man to her mother. Shaw also said a forensic interviewer at Urbana's Child Advocacy center and sheriff's investigators interviewed the girl, and that the girl's statements about the inappropriate contact were consistent.
